poly(NIPAAm)

polymer

Poly(N-isopropylacrylamide) or poly(NIPAAm) is a synthetic polymer that exhibits a well-defined lower critical solution temperature (LCST), making it thermally responsive—it undergoes significant changes in solubility and hydration state around 32°C in aqueous solutions. This material is primarily used in research and emerging biomedical applications rather than high-volume industrial production, where its tunable phase-transition behavior enables intelligent drug delivery systems, temperature-responsive hydrogels, and biomedical devices that can respond dynamically to body temperature changes.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
